Invited Symposium: Nonlinear Dynamical Systems in Psychiatry
Assuming that the depressive syndrome is a cerebral ' dynamical disease ', this study investigates the relation between mood improvement and brain dynamics along depressed patients' therapy. The evolution of brain activity and mood were studied, every two days, for three patients during treatment and for a control subject over three weeks. For each recording session, self-assessment of mood was performed and the brain dynamics complexity was characterized by entropy maps. This study shows a specific organization of depressed brain dynamics and its co-variation with depressive mood. The remission of depressive state has been associated with brain dynamics bifurcation.
